A fully-featured Casio Fx702p emulator including the calculator mode, a full basic implementation and a original debugger as well as some sample programs. The FX-702P was Casio's answer to Sharp's PC-121x series. In certain ways, this machine marks the transition from keystroke programmables such as the FX-601P/602P to "real" pocket computers. On the one hand, Casio labeled the FX-702P only as "Programmable Calculator", and its non-QWERTY layout of the alphanumerical keys differentiate it from most later pocket computers. On the other hand, the FX-702P had a viable BASIC interpreter which allows for more flexible programming. The built-in interpreter supports a variant of the BASIC language, with some keywords spelled in a different way than the later quasi-standard, e.g. PRT instead of PRINT, or GSB and RET for GOSUB and RETURN. Compared to Sharp's PC-121x models, it has substantially more mathematical and statistical functions, string manipulation functions and a more flexible variable handling scheme.

I had an fx880p so I can compare it with the real thing. touch is ok, but keys are a tad too small. So it sometimes does not register, because your finger is actually pressing a neighbour. For typing fast, other programs with bigger keys exist that do the job well too and have more display & recall.
